		<br><div id="orangeText">Description</div>
		<p>This step does not continue from the previous steps. It shows a hexahedra mesh which already has mechanical behavior and could be also linked to a surface mesh.</p> 

		<div id="orangeText">Key points</div>
        
        <div id="tutorialAction"><p>Press the <strong>Edit in Modeler</strong> button at the top of this window.</p></div>
        
        <p>This opens a pre-built scene graph in the Modeler.</p>
        
        <p> This scene includes components we are already familiar with:</p>
        <p>
        <ul>
		  <li>An ODE solver and a linear solver. </li>
		  <li><b>MechanicalObject</b> with geometry point positions.</li>
		  <li><b>RegularGridTopology</b> is used to create a 3D grid mesh. </li>
		  <li><b>HexahedronFEMForcefield</b> is used to create tetrahedral finite elements on this mechanical system.</li>
		  <li><b>DiagonalMass</b> describes a global mass of the mesh elements.</li>
		  <li><b>Constraint</b> components are used here to fix the four corners of the upper face of the cube.</li>		  
		</ul>
        </p>

        <div id="tutorialAction"><p>Run in SOFA and animate. Interact with the cube by holding the <strong>Shift</strong> key and dragging with the mouse.</p></div>
        
		<p>This scene represents a 3D cube mesh under gravity. It is the same configuration as the step <a href="2_TopoMapping.scn">"Embedding the Model"</a>.</p>
